No idea why this is happening. Ran for a few months with no problems with 3 7950s.
Thought pci risers needed molex, added them. Replaced mobo. Have a 850w psu so tried only running two gpus, still freezing. Weird that it used to run fine and will run great for 30 mins then stop. Temps are fine, below 70c.
Any insight would be greatly appreciated.
Love,
Bobby
